Question

Enter the correct value so that each expression is a perfect-square trinomial.

Answer 1

2x-10x+
It’s answer is 25

Answer 2

Answer:

$x^2-10x+25$

Step-by-step explanation:

We have been given an expression $x^2-10x+$. We are asked to convert our given expression into perfect-square trinomial.

We know that an equation in form $x^2+bx+c$ is a perfect square, if $c=(\frac{b}{2})^2$

To convert our given expression into perfect-square trinomial, we need to add $(\frac{10}{2})^2$ to our given expression.

$(\frac{10}{2})^2=5^2=25$

Therefore, our perfect square trianominal would be $x^2-10x+25$.
